The aim of this thesis work is to design and manufacture a Dissimilar Channel Angular Pressing (DCAP) system for severe plastic deformation of aluminum alloy sheets in order to obtain ultra-fine grained structure. First, a DCAP system was designed by Finite Element Analysis and constructed after various optimization trials. Next, 6061-T0 aluminum alloy plates were severely deformed by various DCAP passes through the system. The samples were characterized by metallography, X-ray diffraction, tension and hardness tests. It has been observed that the yield strength was improved about 100 % after 2 DCAP passes, and 45 nm sub-grain size was obtained.

Characterization of ultra-fine grained steel samples produced by high pressure torsion via magnetic barkhausen noise analysis Bayramoğlu, Sadık; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2009) High Pressure Torsion (HPT) is one of the most widely used severe plastic deformation methods which enable to obtain a crack free ultra-fine grained bulk material with improved mechanical properties like increased strength and toughness. In the process, a disc shaped sample is pressed between two anvils and deformed via surface friction forces by rotating one of the anvils. The aim of this study is to nondestructively characterize the variations in the deformation uniformity of the severely deformed steel d...
Production and characterization of high performance al – fe – v – si alloys for elevated temperature applications Sayılgan, Seda; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2009) In the present study, the powder metallurgy was evaluated as a technique to produce high performance Al – 8Fe – 1.7V – 7.9Si (wt%) alloys for elevated temperature applications and the role of powder particle size range and extrusion ratio in the microstructural and mechanical properties of the extruded alloys was investigated. For this purpose, an air atomization method was employed to produce powders of the high temperature alloy and after that the produced powders were sieved and cold compacted. The compa...
Investigation of the effect of dissimilar channel angular pressing method to the mechanical and microstuctural properties of 6061 aluminum alloy sheets Kibar, Alp Aykut; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2010) Dissimilar Channel Angular Pressing (DCAP) method is an effective Severe Plastic Deformation (SPD) technique to improve the mechanical properties of sheets or strips by producing ultrafine grains. The aim of this study is to investigate the evolution of the microstructure and the improvement in mechanical properties of 6061 Al-alloy strips deformed by DCAP up to 5 passes. Mechanical properties such as hardness and strength have been observed to increase up to a certain strain level depending on the microstr...
Ternary nanocomposites of high density, linear low density and low density polyethylenes Uçar, Egemen; Yılmazer, Ülkü; Department of Polymer Science and Technology (2007) In this study, the effects of organoclay loading, compatibilizer loading and polyethylene type on the morphology, rheology, thermal properties and mechanical properties of polyethylene/compatibilizer/organoclay nanocomposites were investigated. As compatibilizer, terpolymer of ethylene-methacrylate-glycidyl methacrylate (Lotader® AX8900), as organoclay Cloisite® 15A were used. All samples were prepared by a co-rotating twin screw extruder, followed by injection molding. Considering ternary nanocomposites, h...
Production of coal crusher hammer heads by bi-metal casting Kırma, Turgut; Selçuk, Ekrem; Department of Metallurgical and Materials Engineering (2008) In this study, by considering different mechanical properties such as wear resistance and toughness of two different metal alloys in design and production stages, bi-metal casting technique was used for producing composite material which will be a solution for the cracking and wear problem in coal crushing hammer heads. The failure analysis of the classical hammer heads which are made from Hadfield steels (austenitic steel) showed that there are crack formations through austenitic grains and also the phase ...
